The Workload Planner then compares the two values to the maximum response time associated with its given service level. If both calculated values fall within (under) the service level defined response time band, the compliance state is STABLEhttps://www.dell.com/support/kbdoc/en-us/000022528/how-does-the-workload-planner-function

Step by Step Comprehensive Detailed Explanation:

The symsan command in Solutions Enabler is used for various SAN (Storage Area Network) management tasks. One of its functions is to scan the SAN environment to discover and verify the configuration of devices and paths.

When used in the context of an Open Replicator Migrator for Dell EMC (O-MDM) session, the symsan command specifically:

Verifies SAN Configuration:It checks the connectivity and configuration of the SAN fabric to ensure that the source and target devices are accessible and properly configured for the migration.

Non-Disruptive:It performs this verification without disrupting any applications or host I/O operations on the remote host. This is crucial for maintaining business continuity during the migration planning phase.

Why other options are incorrect:

A. Temporarily stops the remote application to verify the SAN configuration:symsan does not stop applications; it performs a non-disruptive scan.

B. Verifies the SAN configuration and creates an ORS session on the remote host:symsan only verifies the SAN; it doesn't create ORS (Open Replicator Solutions) sessions.

D. Temporarily stops the remote application and creates an ORS session:Again, symsan doesn't stop applications or create ORS sessions.

Host I/O Limits in PowerMax allow you to control the maximum IOPS (Input/Output Operations Per Second) or bandwidth that a storage group can consume. This helps prevent performance issues caused by one application or workload monopolizing resources.

When you associate Host I/O Limits with a Storage Group, the default Dynamic I/O distribution mode is set toNever.

Never:This means that the I/O limits are statically distributed across the directors in the associated masking view. If a director fails, its allocated portion of the I/O limit is lost. This is the most conservative setting, as it ensures that the I/O limits are strictly enforced even in the event of a director failure.

You can change this setting toBalancedorAlwaysif you need more dynamic distribution of I/O limits.
